All they have to do is increase their subsidies and incentives to companies in the renewable energy industry, create an easy to entry barrier with full Govt support, these Co.s will then invest the money in R&D and very soon there will be the advent of a new breakthrough in technology which will be cheaper than the current energy sources we have today.

This, in place of taxing CO2 and every molecule out there with out including H2O and O2.

I am researching the current energy and renewable energy issues facing the world. The task is very extensive and complicated. Each region has renewable energy opportunities that can be important to environmental issues, economic development, and social needs for all humans. Government agencies, industry, agriculture, educational and research organizations are focused upon massive research efforts. This seems to provide a way to share information, thoughts and ways to help people to improve our lives by conserving energy, find alternative energy resources and realize that fossil fuels are depleting and non-renewable. Can renewable energy be a way to produce additional energy? Networking can provide valuable information to further the advancement of changing habits about energy. I am a farmer with a background in sustainable energy and educational degrees in agriculture. A sustainable energy for industrial and developing countries can improve the quality of life of all human beings.

Sources for renewable energy are all around us. When you say renewable energy the first things that always come to mind are wind and solar power. These two technologies have been the primary focus for discussions about renewable energy for quite some time. Complimented by geothermal energy and biomass production, these four get 99% of the attention when it comes to renewable energy sources. However there are many more potential sources for renewable energy sources in today’s world and it is going to take a broad approach utilizing multiple technologies to truly solve our current energy problems.

The big four sources of renewable energy have gotten the most media and government attention because they all at one point in time were thought to have the potential to be the silver bullet for the energy problem. They were all supposed to be THE solution to our growing demand for energy and dependence on foreign resources. However, it has become quite apparent that no one of these technologies alone can actually provide that kind cure all effect, thus it is time for us to take a broader look at the potential sources of renewable energy around us.

Anywhere there is motion; there is energy being spent and energy that can be captured. The goal of renewable energy sources are to find naturally occurring or wasteful sources of motion and harness this motion to create energy. This is precisely what wind turbines do, they harness the motion of the wind to turn a generator and make power. This same idea can be applied anywhere that here is naturally occurring motion. One example that has actually been tried with some success but needs further development is river turbines.

Of course hydro power has been around for a long time inside of dams, but the building of reservoirs and flooding of land is tremendously harmful to the natural environment. The river turbines of the future will simply harness the natural flow of a river to turn a generator. They will be similar to wind turbines, with blades that extend out into the river current. These turbines could be sunk into the bottom of deep sections of river and have no noticeable effects on the area around them. These river turbines however need to be incredibly durable and low maintenance, which is part of the reason they have only seen limited success and use thus far. However, with further development it is quite possible that they could become a very reliable source of renewable energy.

Another naturally occurring source of motion is the ocean. Ocean’s are constantly in motion, between wave action and tidal changes there is a lot of potential energy that would capture. There have been several different attempted technologies for capturing the motion of the ocean for energy purposes, but they have not received much attention. One major difficulty is the harshness of the environment in the ocean, which corrodes metals and is generally a treacherous environment. Again though, there is a huge potential for renewable energy in this as of yet unutilized source, it will simply take smart development of new technologies.

Turning to wasted potential from human endeavors the smoke pouring out of manufacturing facilities around the country is a prime example of wasted motion. There are several technologies in place and underdevelopment that take this motion of hot air up smokestacks and use it to generate electricity. You can think of it as a constant wind, as long as the factory is running, there will be air moving up the smoke stack, and if you had something in the smoke stack capturing that potential energy you could use those pollutants to help reduce the strain on the environment from power generation.

It is these kinds of creative solutions that, all put together, will be able to truly impact the way we generate power. No one source of renewable energy will ever provide the silver bullet everyone is looking for and it is time to give up the hunt. We need to invest in and pursue a broad spectrum of renewable technologies, not in the hopes of finding the best one that will solve all of our problems, but with the goal of getting all of them to the point where they can contribute to the overall solution. Simply looking at the world around us will show an untold number of potential renewable energy sources, all it takes is creativity and a commitment to pursue multiple technologies with the hope of developing a diversified renewable energy platform that can replace our current dependence on fossil fuels.

An alternative energy resource, gaining much market share, is solar power. It is the one that is most well known every day. This involves the manufacturing of solar cells which gather and focus the sun’s energy, and translate it into electricity. In some, hot water can be produced from the sun. As with wind energy, solar energy creates absolutely zero pollution.

One of these renewable energy resources is solar energy. Solar PV cells continue to be manufactured that are often more energy efficient and less costly than previous models from a few years ago. Solar energy plants have been developed in in many nations. They are now more strategically placed in order to improve the national electricity grid. Over time, they are not causing environmental issues as previous placement of solar panels may have caused.

The following sections provide a summary overview of many other renewable energy sources being researched, developed, and deployed throughout the world.

Ocean current energy is discussed by governments and investors as having untapped energy generating potential. A ocean electricity generator in Europe has been in operation for a long time. It is thought to be a great accomplishment. The Irish and Scots are also running pilot facilities.

Hydroelectric power has been with us for a while. At current hydro dams, it is a clean generator of electricity. Because water and gravity is used, it is more effecient than a grid powered by natural gas. There are restrictions to the availability of the right places to set up a large dam. Many river based, or small and localized, hydro generators where created in recently due to this limitation.

Geothermal energy is extremely abundant. Since it lies directly beneath us, we only need drill just a few miles below the earth’s surface to find huge amounts of energy. This energy is produced by the heating of water, trapped in layers of rock, through the earth’s hot molten core. The water turns to steam, which is then used to drive turbines that generate electricity. Great amounts of research and development should be put into geothermal energy tapping.

Biodiesel energy is created out of the oils contained in plants. Most commonly, the retail stockpiles of bio-diesel have been created using rapeseed and sunflower oils. At the time of this writing, biodiesel is typically produced by agricultural corporations or those who want to experiment with renewable energy. Venture interest from companies across the World is on the rise. It burns much better than fossil fuel diesel.

Another renewable energy resource is solar generated electricity. Solar PV cells continue to be manufactured that are often more energy efficient and less costly than previous models from a few years ago. This involves the manufacturing of solar panels which gather and focus the sun’s energy, and translate it into electricity. In other cases, hot water can be produced from the sun. As with wind energy, solar energy creates absolutely zero pollution.

Sometimes it takes more than one to push the boundaries of technology. It seems that no matter how much renewable energy marketing is actively propagated it seems that there are just some that can’t maintain their composure and just dissolve in thin air.

Renewable energy company owners are more often than not optimistic that it could sustain a considerable number of houses and can talk owners into converting to solar paneled roof tops to cut energy costs.

First, not all consumers are as optimistic as the company. Sure consumers are open for talks and introductions but purchasing is another thing. Unless current energy resources are all flushed down the toilet, consumers will just find ways in saving up without converting into renewable energy.

Take for example the water powered car. We’ve heard of it and it has been on sale for more than a year but how many people actually owns them? The initial cost of a hydro-car costs as much as $5000 for a two-seater car. For a tiny car, you might want to pause and think.

Second, large scale renewable energy plants require a certain amount of land. In cases of hydro-electric plants a construction of a large dam is a must. It takes money and good fore sight to make everything work.

Dams that are built in a poorly results to unsightly calamities so good fore sight is needed to guarantee stability and of the dam. Energy plants need the luxury of space in order to operate properly. On the other hand, in most parts of the world, space is scarce and is demand than ever.

Third, it is too darn costly at the start. Unless a renewable energy company is an off shoot of a larger more stable company, small renewable energy company crumbles within the first few years of it being established.

The demand for renewable energy materials are is just too low at the moment. No matter how aware people are, converting their household into eco friendly homes may take them a back before they try it out. It takes weeks of thinking before people change all their lighting from incandescent to energy saving fluorescent bulbs.

How much more thinking would you think it will require for them to install a solar panel or a wind mill to cut down energy costs by half?

Fourth, innovator and manufacturer misunderstanding can lead the renewable energy company to crumble. If the company is dependent on a manufacturer other than them manufacturing the products, misunderstanding can easily break the ties of the two companies. Thus leading the other to fall apart and die.

It is a different case however if the company manufacture their own products. Nonetheless, small scale renewable energy companies can not afford such production especially if small quantities are asked to be produced.

Production cost would be higher therefore market price is higher than mainstream renewable energy companies.

Lastly, after the hype of renewable energy marketing, the idea burns out and takes an exit on the scene. Harsh but true, once local television networks stops advocating the use of it, the hype disappears and so is the hope of selling these products.

Renewable energy has its uses but they aren’t all advantageous. In this piece some of the benefits and adverse effects of renewable energy are considered and examined in different forms of renewable energy.

When people think or energy sources, they mostly think of coal, natural gas and oil, these fuels have been the source of energy for a number of years. However one problem is that they are limited in supply and availability.

Estimates have shown that the currently available sources will only meet our current energy demands for about 50 to 70 years or so. In order to find alternative sources of energy the world has decided to pursue renewable energy sources. However even renewable energy sources have their advantages and disadvantages too.

The available renewable energy sources that we have include solar, hydro, wind, geothermal, ocean and biomass. The most common of these advantages is that they are clean energy sources and do not pollute the air. They also do not contribute to global warming or greenhouse effects. Because the sources of such energy are natural the cost of operations are substantially reduced and they require less maintenance on their plants. One common disadvantage is that it is impossible to produce large quantities of electricity than can be done with fossil fuels. Because they are new technologies the costs of initiating them is also high.

Solar energy utilizes the energy from the sun. It has its advantages because these systems can easily fit into existing buildings and do not affect land use. Since the area that these collectors rest in is quite large, a lot more materials are needed. Solar radiation is also controlled by geography too. It is also limited to the daytime as well as non-cloudy days.

Wind energy makes use of the power of the wind in order to create electricity. Though it produces the most jobs it is reliant on strong winds too. Wind turbines tend to be large and though the areas under them can be used for farming, most people think of them as unattractive looking. These turbines are also very noisy to operate and they threaten the population of wild birds too.

Hydroelectric energy makes use of water in order to produce power. It is the most reliable of all energy sources that are renewable. Its disadvantages are that it affects the ecology and causes downstream problems. Decay of vegetation on the riverbed can also cause a buildup of methane which contributes to the greenhouse effects. Dams may also cause an alteration of the natural river flow and affect wildlife in the area as well. Water which is colder and which is lacking in oxygen tends to be released into the water this kills the fish, sudden release of water like this may also result in flooding.

Geothermal energy makes use of the steam from the Earth’s ground in order to generate power. It uses a smaller land area that other types of power plants. They can literally run continuously throughout the year. The disadvantages tend to be that these plants are site specific and it can bring up toxic chemicals and heat from the earth when it tries to obtain the steam. Drilling such geothermal reservoirs can also cost a lot.

Biomass electricity is made from the energies of wood, agricultural and municipal waste. It tends to help save on landfill waste but the transportation is also expensive and tends to affect the diversity of the land. Other than this the process is quite complex and should be much simpler.

Ocean energy is a clean and abundant energy form. It tends to be expensive and in order to access this energy, you need at least a 40 degree Fahrenheit difference in water temperature throughout the year. Other than this, the construction and putting in place of pipes may damage the ecosystem.
